When most people think about building a mobile app, their minds go straight to native development. Native apps are built specifically for certain platforms, like iOS or Android.

Don’t get me wrong; I won’t sit here and say that there aren’t advantages to taking the native route. But with that said, native development will likely be your most expensive path.

On the other hand, cross-platform development is rising in popularity.
In fact, the cross-platform app development market surpassed $7.5 billion at the end of 2018.

This development method allows you to develop an app for Android, iOS, and Windows simultaneously. But can these apps be as good as native apps?
Honestly, if you use the right tools and resources, users won’t be able to tell the difference.

But where do you begin? What tools do you use for cross-platform development?
These are common questions that I hear on a regular basis. That was my inspiration for creating this guide.

I’ve created the ultimate resource of development tools, programming languages, and tutorials for cross-platform development. This will put you in a position to build a mobile app that’s ad no disadvantage compared to traditional native apps.
Plus, you’ll have the benefit of reaching users across different platforms with just one app.

Cross-platform development is the way of the future. I highly recommend using this guide as a reference and learning tool.

The Best Cross Platform Development Tools
First things first; If you’re going to build a cross-platform app, you need to pick a development tool. I’ve narrowed down the top options to consider based on ease of use and outstanding performance.
These are the most popular choices in terms of quality. So check them out and decide which one is best for your specific needs.

Appcelerator
Appcelerator is a development platform focused on enterprise solutions. The tool helps get apps to market faster by simplifying the cross-platform development process.
Developers can use a single JavaScript code base for native apps and cloud-based mobile apps as well. This code can be used for apps on any device or operating system.
Another top benefit of Appcelerator is their quality assurance. They make it easy for you to verify your apps using automated mobile tests. You’ll also be able to measure usage and results of your projects to detect bugs, crashes, and make adjustments to improve the performance.
The API builder allows you to mobilize all of your data in just minutes. This makes it easier for you to scale.
All Appcelerator developers will have access to Hyperloop for free. This is one of the strongest and most robust cross-platform APIs on the market.

PhoneGap
PhoneGap is owned by Adobe—a company with a reputation that speaks for itself. This is definitely one of the most popular cross-platform development options within the developer community.
It’s based on the open source Apache Cordova. This open source framework gives you access to the PhoneGap toolset, which makes it possible for you to get to market faster.

One of the reasons why I like PhoneGap is because you have access to guides that are specifically for their platform. Anyone can learn how to use their tools, even if you don’t have experience with them.
For those of you who already have web development skills, there won’t be much of a learning curve when it comes to making hybrid apps. PhoneGap uses JavaScript, HTML, and CSS to build cross-platform apps using a single code base.
Once you’re done building, you don’t need to maintain native SDKs. The PhoneGap build service takes care of all of this for you by compiling your work in the cloud.

Xamarin
Xamarin is a product from Microsoft Visual Studio. It allows you to build apps for iOS, Android, and Windows using a single .net code.
All apps built with Xamarin look and feel like they are native apps. That’s because Xamarin uses native interfaces that behave the way a user would expect them to.
If you use Xamarin, your app will have platform-specific hardware boosts that are compiled to achieve native performance. This isn’t the case with alternative solutions that need to interpret code at runtime.
More than 75% of your code will be the same, regardless of the platform you’re building for. Xamarin identifies the similar code and accelerates the process for cross-platform development.
You can access their IDEs on whichever platform you prefer. The visual studio is available for both Mac and PC. Both systems come with publishing tools, debugging, UI design, and code editing.

Redhat
Formerly known as FreedHenry, Redhat is a global resource of open source solutions. They offer specific services for cross-platform development and mobile backend.
This lets enterprises develop and launch mobile apps for Android, iOS, and Windows simultaneously via the cloud.
Here are some of Redhat’s tools that are specific to app development:

OpenShift application runtimes
OpenShift application container platform
Developer studio
Decision manager
Data grid
Process automation manager
JBoss enterprise application platform
JBoss web server

As you can see, they have a wide variety of tools that will help you with your cross-platform development needs.

Alpha Software
Alpha Software is a solution for enterprises. The main purpose of this software is to build business apps that are intended for employee usage.
If your company doesn’t issue smartphones to your employees, then it’s a safe assumption that everyone will be using different platforms. That’s why you need to use a cross-platform development tool to build your app.

Some common features built with Alpha Software include:
Event reports
Work orders
Field research
Signature capture
Medical forms
Safety checklists
Equipment inspections
Service dispatch

These types of functions are versatile enough to accommodate enterprises in any industry. Alpha Software offers a 30-day free trial. So at the very least, it’s worth trying out.

Sencha Ext JS
With Sencha Ext JS, you can build cross-platform web applications for smartphones, tablets, and desktops. This is a top option for those of you who need to build an app that’s data-intensive.
The framework uses HTML5 functionality for modern browsers. All of the UI components have been previously integrated and tested for optimal performance.
Some of the available components include grids, forms, menus, panels, toolbars, trees, and lists. There are also hundreds of extensions available for complete customization when you’re building.

Sencha offers a sophisticated data visualization table, making it easier for you to track extensive information. The Ext JS data package is robust and highly functional with a flexible layout manager. This makes it possible for you to organize how your content is displayed based on device, screen size, and browser.
Sencha also has an accessibility package that’s Section 508 compliant, which is a huge benefit it, considering the fact that app accessibility is the new must in mobile development.

Kony Quantum
Kony Quantum is an easier way to build mobile apps for multiple platforms. That’s because they have a visual canvas with pre-built components for you to choose from.
You can use Kony to create new apps or improve existing apps as well.
This tool is great for inexperienced developers. They provide guided tours and single-click cloud builds throughout the process. It’s easy to integrate data, which will eventually be put on a visual data map to enhance productivity.
The end result of your cross-platform development project will be modern, beautiful, and entice an engaging experience for the user.

Alternative Cross Platform Editors and IDEs
For those of you who want to create a basic mobile app or need something that’s more niche-specific, you’ll definitely want to look through these alternative editors and IDEs.

The options below aren’t necessarily as popular as the major cross-platform development tools that we’ve seen so far, but they’re still very helpful and easy to learn.

Mobincube
Mobincube is a multi-platform tool used to build native multiplatform apps for Android and iOS. More than 193,000 apps have been published by Mobincube users.
Furthermore, apps created with this tool have resulted in more than 238 million downloads. This has resulted in over $3.2 million in revenue for developers.
It’s free to sign up for Mobincube and it’s very easy to use. If you want additional features like app store optimization, ad removal, and cloud user management, you’ll need to upgrade to one of their premium plans.

IntelliJ IDEA
IntelliJ IDEA is an open source product from JetBrains. Right out of the box developers will get the tools and version controls they need to support a wide range of frameworks and programming languages, without having to install any plugins.
It’s mainly used with Java development for Android, but with that said, it can also be used for cross-platform development.

Qt
According to their website, Qt claims that eight out of the top ten Fortune 500 companies use their products.
Qt is great for rapid development, deployment, and prototyping. The IDE and UI tools are intended for both developers and designers. The platform is reliable, stable, and yields high-performing results.
Their cross-platform development framework makes it possible for businesses to use a single codebase with common APIs to support all mobile platforms.

Corona uses Lua, which is an open source programming language. It’s fast, lightweight, and powerful. Some of the world’s most popular games like Angry Birds and Warcraft use Lua.

This is a free cross-platform resource. Everything you build can be deployed on all devices with just one code base.

Ionic
Millions of developers have used Ionic to build their apps. The JavaScript framework supports cross-platform development. Their open source UI toolkit can be used to develop native Android, iOS, and web applications using a single code base.

Ionic also has tons of guides and resources to help you get through the building process. The newest version of this editor claims to be smaller, faster, and more extensible than ever before.

You’ll need to install Ionic Studio locally onto your device. But the visual editor makes it easy for you to build apps fast.

Yapp
Yapp is used for making a very specific type of application. You can use this platform to create cross-platform apps for conferences, events, and meetings.
It’s essentially a way for companies to run an event by going paperless. This improves the accuracy of information given to attendees and guests whenever you need to make last minute changes. You can create and send push notifications to guests with reminders about the schedule as well.

So for those of you who are looking to build an app to manage your events, I’d definitely recommend using Yapp.

RubyMotion
As the name implies, RubyMotion is made for writing cross-platform native apps with the Ruby programming language. With RubyMotion, all of the applications are built using the terminal command line. So you’ll be able to use your favorite editor, as opposed to learning how to use a new one.

Once your code gets written in the interactive console, the real-time changes will be integrated to third-party libraries. From there, RubyMotion has a built-in debugger to help you identify any problems. There is an automated testing framework integrated into this platform as well.

Dropsource
Compared to some of the other editors and IDEs on our list, Dropsource is a fairly newer alternative. It’s a browser-based platform, so you don’t need to install anything on your machine.

You can build cross-platform native apps using Swift and Java. Just because it’s a browser-based editor, it doesn’t mean you lose mobile functionality. You can still add elements like geolocation, face ID, touch ID, push notifications, and video recording to your app.

Dropsource has a visual editor and REST API, which is ideal for seamless data integrations. It’s easy to update your app with their drag and drop process.

AppsMoment
AppsMoment has been on the market for six years. During that time their platform has been used to help more than 60,000 people publish over 700,000 apps.
No coding is required to build these cross-platform mobile apps. They have over 500 app templates and 120 features for you to speed up the building process.

Xojo
At a minimum, the majority of the cross-platform tools we’ve seen so far have the ability to build apps for mobile, web, and desktop. Xojo stands out from the crowd because it’s compatible with all of these but also lets you develop with Raspberry Pi.

It’s easy for developers to build a native interface quickly with the drag and drop UI. This makes Xojo a top option for beginners.

I’d also recommend their community forums, which can be a useful resource to get help and clarification whenever you’re stuck. Xojo also has tons of tutorials, video demonstrations, textbooks, and example projects to ease the learning curve.

Progress Kinvey
Progress Kinvey is made for web developers who already have JavaScript skills. With prior JS knowledge, you can easily build cross-platform native apps for Android and iOS.

The web-based development studio is made to enhance productivity. As a developer, you can focus on the business side and user experience of your app, while the platform automatically adjusts to scale accordingly.

Mag+
Mag+ has digital publishing software intended for building mobile business apps across multiple platforms. Their SDK simplifies the process for publishing content to your app.

You can design, build, distribute, and publish your app all with the help of Mag+ tools.

It’s not as popular as some of the other tools on our list. Less than 5,000 apps have been built with their platform. But with that said, big names like Volvo, United Airlines, and the Harvard Business School have created apps with Mag+.
I’d recommend it for things like internal newsletter applications, sales presentations, branded magazines, and product catalogs.

Programming Languages
The majority of cross-platform editors and IDEs all operate under the same premise. Developers use one code base to build their app.
If you know more languages for the coding environments, you’ll have more options when it comes to choosing the best tool for building your cross-platform app.
Not every programming language is the same. Some are new, some are old, and others are more known for native development on specific platforms. Either way, I’ve narrowed down the top cross-platform development languages for you to consider for your project.

JavaScript
JavaScript is one of the core elements of the Internet. It’s essential for web applications and interactive web pages. Most major websites use JavaScript, and web browsers typically have dedicated JS engines to execute its functionality.
This is probably one of the best programming languages for beginners who are new to coding. For those of you who have a background in web development, it will be easier to build a cross-platform mobile app using JS.

Java
Java is another top choice for cross-platform development. There aren’t many downsides to using this programming language to build any type of app since it’s compatible nearly anywhere.

Java is known for keeping costs low, driving innovation, and improving app services. It’s the go-to language for cloud computing and enterprise architecture.

Ruby
Ruby is a newer programming language that’s open source. It’s meant to be as simple and lightweight as possible. Unlike some of the other languages, Ruby was designed specifically for mobile applications.
People like Ruby because the syntax is easy to write and reads naturally.

C++
As a general-purpose programming language, C++ is seemingly everywhere. It runs on platforms like Mac, Windows, Unix, and Linux.
It probably shouldn’t be your first choice for cross-platform mobile apps, since it can add some strain to mobile resources.

C#
C# is becoming one of the most popular languages for cross-platform web applications. What Objective-C is for Mac, C# is for Microsoft.
If you’re familiar with Java, C++, or C, then it will be easy for you to recognize and pick up C#. This object-oriented language can be learned fairly quickly.

HTML5
HTML5 is at its strongest when paired with JavaScript. It’s the fifth version of the HTML standard, used to define behaviors and properties of content on web pages.
This programming language will help make your app compatible with desktops.
Cross Platform Language Tutorials
Now that we’ve identified the cross-platform programming languages, you need to learn how to use them. I’ll show you the top tutorials for each language that we covered above.

JavaScript language tutorials
If you want to learn JavaScript, look no farther than these three tutorials.

Mozilla Developer Network
The Mozilla Developer Network is a top resource for building cross-platform apps. In addition to JavaScript, MDN teaches you the basics of HTML and CSS. Without this foundation, it will be challenging for you to learn JS.
MDN has modules for JavaScript first steps, building blocks, objects, and client-side APIs. You’ll also have access to some of the most common problems and solutions with this language.

/r/LearnJavaScript
Most people wouldn’t think to turn to Reddit to learn a programming language. But this discussion thread is updated on a regular basis. It’s a great resource for asking questions amongst your peers.
More than 56,000 people are part of the r/learnjavascript community. Moderators and active members are constantly posting content to keep the thread alive. I’d recommend joining this Reddit community.

They have a 53-video playlist on HTML5. I highly recommend these for beginners and experienced developers alike. The videos are quick and informative, with the majority falling somewhere in the 5-10 minute range.

Codecademy
You could argue that Codecademy is the best online resource for learning to code online. They’ve been operating for more than seven years. During that time, over 45 million people have used this resource to learn coding.

Codecademy has a wide range of development and programming tutorials. Teaching HTML5 is definitely one of their specialties.

HTML-5-Tutorial
The HTML-5-Tutorial resource was developed for beginners. It’s definitely not the flashiest or most professional website you’ll find online. But with that said, you’ll still have access to tons of great content that will teach you the basics of HTML-5 in plain English.

Conclusion
Your mobile app needs to be available on as many platforms as possible. But building separate apps for each platform can be an expensive and time-consuming path.

That’s why you need to take advantage of as many cross-platform development tools as possible.

Find a tool that you can use to manage all of your development needs. There are certain tools and programming languages that are more specific than others. For example, some editors and IDEs are geared toward enterprises, internal business apps, or gaming apps used by app development company and World wide dev firms.

While other tools and languages are general purpose and have a much broader scope.

Regardless of your cross-platform development project, I’d recommend keeping this guide available as a reference.
